No cultivar name of record

This patent does not name the plant. Through the 1980s and early 1990s that was still common: naming every new cultivar only became standard practice as plants began to be marketed under brand names. The grant identifies this one by its number and by a written description instead.

Nothing here is missing from our records: the patent itself states no name. Where one exists we show it, and we do not invent one.

Abstract

This invention relates to a new and distinct variety of pistachio tree primarily identified by its rounded upright growth habit, abundant foliage and its production of female flowers and seed.

Show the legal claimThe single numbered claim as granted — the legal text that defines what this patent covers.

The following is claimed: 1. A new and distinct variety of pistachio tree (identified as PN-83-F) characterized by a mature tree of rounded upright shape, having several main branches; rapid growth, abundant, leathery foliage, ease of propagation by budding or grafting; and further characterized by the abundant production of female flowers, in clusters, followed by seeds which are especially desirable for planting (when pollenized by the male variety, identified as PN-46-M), said hybrid seeds producing a fast growing, disease resistant tree of value for use as understock upon which to bud or graft commercial nut bearing varieties of pistachio such as `Kerman`.
